Knead in all the ingredients with your hands. Take portions of the meat mixture and make ping-pong or egg sized balls. Fry them in extra-virgin olive oil, on a moderate flame, turning around several times. Put the cooked meatballs on a dish and keep warm. Make a simple tomato sauce with fresh or tinned tomatoes, salt and pepper, a pinch of sugar and a little red wine, add the meatballs and the olives and simmer for 15 minutes. Serve with rice.
